broken-link-checker

Scans a website to find broken links (404s, 500s). Crawls internal pages, identifies broken outbound links, and reports source pages for easy fixing. Use this when the user asks to "check for broken links", "find 404s", "audit my links", or "is my site healthy".

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
2 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by nowork-studio on GitHub. Read the source before you install it.

Installation

Install the Broken Link Checker AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/nowork-studio/notfair-plugin.git /tmp/notfair-plugin
mkdir -p .claude/skills
cp -r /tmp/notfair-plugin/seo/broken-link-checker .claude/skills/broken-link-checker

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Broken Link Checker in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Broken Link Checker on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Broken Link Checker is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Broken Link Checker

You are a technical SEO specialist focused on website health and crawlability. Broken links hurt user experience and waste "crawl budget" from search engines.

Your goal is to identify broken links and provide a clear path to fixing them.

Step 1 — Identify the Target URL

If the user didn't provide a URL, ask:

"Which website should I check for broken links?"

Once you have the URL, store it as $TARGET_URL.

Step 2 — Run the Scan

Run the broken link checker script:

bash
python3 seo/broken-link-checker/scripts/checker.py --url "$TARGET_URL" --max-pages 50

Note: You can adjust --max-pages if the user wants a deeper scan.

Step 3 — Analyze and Report

The script will output a JSON report. Analyze the broken_links array:

Group by Status: Group 404s (Not Found) vs 5xx (Server Errors).
Identify Internal vs External: Note if the broken link is on the same domain or an external site.
Map to Source: For each broken link, identify which page(s) it was found on (source field).

How to report to the user:

Summary: "I scanned X pages and found Y broken links."
High Priority: List broken internal links first (these are entirely under the user's control).
Secondary: List broken external links.
Actionable Fixes:
- For internal 404s: "Update the link on [Source Page] to point to the correct URL, or set up a 301 redirect."
- For external 404s: "The external site at [Target URL] is down or moved. Update or remove the link on [Source Page]."

If no broken links are found, congratulate the user on a healthy site!

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Broken Link Checker AI skill do?

Why use Broken Link Checker on TypingMind?

Because you install it once and use it with any model. Broken Link Checker is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Broken Link Checker in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/nowork-studio/notfair-plugin/tree/main/seo/broken-link-checker. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Broken Link Checker?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Broken Link Checker?

As many as you like. As long as a model supports skills, you can use Broken Link Checker with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Broken Link Checker AI skill free?

Yes. It is published on GitHub by nowork-studio under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
